When the POS goes down, the day is over.
Retail IT lives or dies on uptime. We design networks that survive a Bell outage, a printer that won't pair, and a Black Friday that ate the bandwidth.
A POS that's down for thirty minutes during a Saturday rush costs more than a year of managed IT.
4UIT supports independent retailers and small chains across Ottawa on POS stacks including Lightspeed (Retail and Restaurant), Square, Shopify POS, Clover, Vend and Toast. We design networks that prioritise card-present transactions, segment payments off guest WiFi for PCI-DSS scope reduction, and fail over cleanly when an internet drop happens at the worst possible time.
What retailers actually need
Internet that doesn't drop the sale. Most retailers run on a single ISP — usually Bell or Rogers — with no plan for the day it goes down. We deploy SD-WAN with cellular failover so a circuit drop fails to LTE in under 30 seconds; the customer's tap-to-pay still works.
PCI-DSS scope, kept small. Network segmentation puts payments on their own VLAN. Guest WiFi can't see the POS. Back-office workstations can't talk to the payment terminal except through documented paths. PCI scope shrinks; audit cost shrinks with it.
POS hardware that's actually maintained. Receipt printers, cash drawers, barcode scanners — the unglamorous stuff that breaks first. We hold spare units, swap them same-day, and patch the POS hosts on a schedule that respects the trading day.
Multi-site coordination. If you have two or three locations, central inventory, central reporting, and central security policy. One ticket queue for all sites; one phone number for the manager when the receipt printer dies at 4:55 PM on a Saturday.
Loss prevention & cameras
We deploy and integrate IP camera systems (Hikvision, Axis, Verkada) with retention scaled to your loss-prevention review cadence. Footage stays in Canadian-region storage; access logs retained.
The Ottawa specifics
Same-day on-site across the NCR. We've worked downtown, in Westboro, Bayshore, St. Laurent, Carlingwood, Tanger Outlets, Place du Portage. We know which mall has the IT closet next to the cleaning supplies and which carriers actually deliver in which mall.
Common questions.
Can you support multiple locations under one plan?
Yes — multi-site is what SD-WAN was built for. Central management, one ticket queue, one phone number, per-site reporting. Quoted by total endpoint and site count.
What happens when the internet goes down on a Saturday?
With SD-WAN + LTE failover: under 30 seconds to fail over, customer never notices, your POS continues card-present transactions on the cellular path. Without it: you're calling Bell with the rest of the city. We strongly recommend the failover.
How much does PCI compliance actually cost?
Most small retailers qualify for PCI SAQ-A or SAQ-B (depending on POS architecture), which is a self-attestation, not a paid audit. The cost is the technical controls themselves — segmented network, MFA on admin access, logging. Our managed plan includes the controls; the SAQ takes you 1–2 hours per year.
Can you work with our POS vendor's tech support?
Yes — we triage on our end, escalate to the vendor with a clean problem description, and stay on the line until it's resolved. Our customers stop being on hold with Lightspeed for 90 minutes; we do that for them.
What about seasonal demand spikes — can the network handle Black Friday?
We size for peak, not average. If your network is sized for Black Friday and you're paying for it 365 days a year, that's part of the cost discussion. SD-WAN bandwidth bonding helps; so does scheduling non-essential traffic out of peak windows.
